Multiscale Phenomena play an essential role in the dynamics of many complex systems. Owing to their inherent nonlinearity and the involvement of many different length scales, these systems are often only be studied through numerical simulations. The book focused on common structures and problems in fluid dynamics, particle physics and macromolecule simulations. An important aspect of the discussions was the development of simulation techniques for massively parallel computers and recent advances in the construction of special purpose parallel computers.
